In the United States, late night television is the block of television programming intended for broadcast after 11:00 p.m. and usually through 2:00 a.m. Eastern and Pacific Time (ET/PT), leading out of prime time; informally, the daypart can include the designated overnight graveyard slot. Most notably, the type of programming that has been traditionally showcased in the daypart—most commonly shown after, if not in competition with, local late-evening newscasts—encompasses a particular genre of programming that falls somewhere between a variety show and a talk show.
